Abstract: The present invention is an airbag device mounted on a steering wheel of a vehicle having a rim with a shape in which the distance from the center of rotation to the distance to the upper edges is shorter than to left and right edges, that includes a gas generator that generates an expansion gas and an airbag that expands and deploys toward the occupant due to the expansion gas. Furthermore, at the stage before the occupant comes into contact with the expanded and deployed airbag, the thickness (width) D1 of the upper end part of the airbag in the direction parallel to the rotation axis of the steering wheel when the airbag is viewed from the side is configured to be larger than the thickness (width) D2 of the lower end part.

Abstract: A curtain airbag device that allows easy recognition and correction of twisting of an airbag during attaching. The curtain airbag device can be stored in a compact manner during transportation. The curtain airbag device including an airbag that is disposed along a roof side rail of a vehicle interior, and that can deploy so as to cover a window portion on a side face of the vehicle interior, the curtain airbag device further including a cover that covers the airbag, at least, in a part of the folded or rolled airbag in the longitudinal direction. The cover is formed of a pliable fabric material of polymer fibers, and maintains the shape of the rolled-up airbag through mutual fusion of at least a part of the polymer fibers. A high stiffness portion harder than other portions and formed during the fusion of the cover is provided in the cover extending in the longitudinal direction of the cover.

Abstract: A driver side airbag device with an airbag module including a steering wheel, an inflator, and a cushion. The steering wheel includes a housing portion that stores the airbag module and a cover member that seals the housing portion. The cover member has a design region on an occupant side, and a thin-walled portion formed from an upper portion region to a lower portion region of the design region that is cleaved open by an expansion pressure of the cushion to open cover doors. The thin-walled portion has a first plate thickness portion and a second plate thickness portion that is thinner than the first plate thickness portion. The second plate thickness portion is formed in the lower portion region of the design region.
